FEEDING DEVIGE FOR RETORTS AND THE LIKE.

Specification of Letters Patent.

Patented Dec. '8, 1908.

Application filed J'anuary 14, 1907. Serial No. 352,142.

To all whom it may concern:

dent of Stettin, Germany, have invented certain new and useful'lmproveinents in Feeding Devices for Retorts and the Like, of

which the following is a specification.

- My invention relates to devices for feeding the material to be treated to retorts and the like, particularly when such retorts are arran ed in a plurality of rows.

'l he object of my invention is to ro vide a simple feed device of the above lndicated character, in which provision. is madefor dis charging material from the device to one side or the other 'soas to reach retorts of different rows.

Reference is to be had to the accompanying drawings illustrating two forms 0f 1ny'in* vention, and in which Figure 1 is'a side elevation showing my improved feed device'i-n relation to two retorts,-the parts being in the position of rest; Fig. 2 is a substantially central section through such device taken at rightangles to Fig. 1; Fig. 3 is'a side elevation of a portion of the device in the operative position; Fig. 4c is a view corresponding to- Fig. 1, but show ing the parts in the operative position; Fig. 5

is a side elevation showing the second form of my invention in the position of rest; and Fig. 6 shows the said-form in the operative position.

Referring to Figs. 1 'to 4 inclusive, I have shown a carriagel adapted to travel on suitable rails, so that it can be moved to different positions, and when the retorts are in rows extending parallel with the track on which the carriage runs, the relative position of track and retorts is such that the-carriage adjacent rows ofretorts, such as indicated at 36 and37 in Fig. 1; The carriage comprises a box or receptacle having a bottr'im opening, which in the position 01 rest is closed by a swinging gate 2,"connoc'tcd with a rock shaft 3, which may be operated from either end by means of a hand lever 4. At each side of the receptacle are located guides 5 on which are adapted to move up and down slides 6,

which are'locked in their upper position by means of spring hooks 7 carried by the slides and adapted to engage catches 8 secured to receptacle 1. At the lower portion' of each slide 6, two bolts 9 are mounted to move horizontally in suitabie. guides, the inner ends of such bolts having pins 10 projecting into s 'iral slots or cam slots 11, upon a retary iisk 12, which disk may be turned-in one direction or the other by means of a handle 13. Thus the bolts may either be drawn inward as shown in Fig. 3, or shot outward as illustrated in Fig. 2. In the lat ter case, the outer ends of the bolts 9 will pass thro h eyes 14 at the ends. of lever arms 15, w ich are secured to chain-wheels 16'loosely mountedupon the shaft 3 exteriorly of the receptacle 1. By means of chains 17..the wheels 16 areconnected with another set of chain-wheels 18', secured to a shaft 19. This shaft is journaled in bearings 20, carried at the lower ends of bars 21, 22, secured to the receptacle 1. To the shaft 1% are also rigidly secured arms 23, 24, carry+ ing attheir free ends bearings 25, 26, for the trunnion pins 27, 28, of a suspended hopper 29.

Immediately below the bottom openi of the receptacle 1, the bars 21, 22 on both sides thereof arev connected by cross pieces 30 provided with inwardly projecting pins 31.

tudinalslot 32 of a guide-bar 33, which is see cured to the side of a chute 3 1, so that the chute may be slid back and forth-on the pins 31 immediately beneath the opening of the receptacle 1, and may also be tilted in one direction or theother. The tilting movement is, however, normally prevented by brackets 35 secured to-the lowcr'ends of the slides 6 and engaging the chute 34..

The mechanism above described is operated as follows: The receptacle l-having been filled with the material to be transferred into the retorts is brought adjacent to the retort which is to be charged. Both slides 6 are supposed to be locked in their upper position by means of the hooks 7 and catches 8. The chute 3 1 is presumed to be in its central position in other respects the parts occupy the position shown in Fig. 1. Then, presuming it is desired to charge the retort 36, the slide 6 shown at the right of Fig. 1 is moved down Fig. 4. Atthe same time the slide moves upward, the chute 34 is tilted as shown, ow-' ing to the factthat it is no longer held in a-- ,horizontallposition by the bracket 35. Thereu on the s aft 3 is turned by means of either 0 the handles 4, so as to open the gate 2; whereupon the contents of the receptacle '1 will pass on to the chute 34 and throu h the hopper 29 into the retort 36. After t e retort has been charged, the slide 6 at the right i hand side is again lowered, whichjbrings the chute 34 back to the position shown by solid lines Fig. 1, and also swings the hopper 29 back to its central position. When it is desired to fill the retort 37 the operation is similar, only that the slide 6 at the left hand side is used, and the chute 34 is moved over toward the right. Fig. 4 shows in dotted lines the position of the various parts at the time of filling the retort 37.

The device described above is very simple in construction and operation and offers the further advantage that in the position of rest there are no parts projecting materially from the carria e, so that the device .will not interfere wit the travel of similar devices for adjoining rows of r'etort's.

The construction illustrated by Fi s. 5 and 6 differs from the one described on y by the means for operating the hopper 29. This hopper is suspended by means of a chain 38, secured to the arm 39 of a lever loosely supported on the shaft 3. This lever is provided with two additional arms 40 and 41 on the other side, the said arms having eyes 42 and 43 respectively, adapted to be engaged by the bolts 9 of one slide-6 or the other. The solid lines in Fig. 5, and Fig. 6, show the lever 3940-4l connected with the right hand slide 6 so as to bring the hopper 29 into registry with the retort 36. The operation is substantially the same as described with referenceto Figs. 1 to 4: That is, while one of the slides 6 is in its. lower position, it is connected with the lever 39-4041, by means of the bolts 9, and then the slide is moved upward to lower thehopper 29 on to the retort and to cause the chute 34 to tilt as shown in Fig. 6. The ate 2 is then operated by means of the andle 4, as previously described. When it is desired to charge the retort 37, the lever 394041 is swung in such a manner that its arm 41 will be adjacent to the left hand slide 6, and the latter having been lowered is connected with said lever by means of the bolts 9, which position is indicated by dotted lines in Fig. 5 The chute 34 is moved over toward the right. Then the left hand slide 6 is raised, causing the ho pper 29 to be'lowered on the retort 37 and the slides 6 will balance the hopper 291and the chute 34 to have an absolute or approximate equilibrium between these parts, so that they Will be moved very easily.
